Damping-off of forest species caused by Sclerotium rolfsii Sacc.

Abstract

The host range of Sclerotium rolfsii was evaluated by controlled inoculation of the following native and exotic forest species: Anadenanthera peregrina (angico vermelho), Chorisia speciosa (paineira rosa), Clitoria fairchildiana (sombreiro), Copaifera langsdorffii (copaíba), Delonix regia (flamboyant vermelho), Enterolobium contortisiliquum (orelha de negro), Leucaena leucocephala (leucena), Mabea fistulifera (canudo-de-pito), Platymiscium pubescens (tamboril da mata), Senna macranthera (fedegoso), Spathodea campanulata (espatódea) e Tabebuia avellanedae (ipê roxo). The fungus caused damping-off in pre and post emergence in all tested species.
